<p>^^^ That’s not toxic in itself, but definitely not a good place to be if you happen to be one of the kids whose mental illness first shows up when you hit 20yo. I’d surely like my kids to be in an environment where someone would notice if they started behaving oddly or withdrawing or displaying other warning signs.</p>
<p>Toxic would be an environment that would <em>cause</em> a kid to have issues (too much stress, for the wrong kid, or not enough sunlight, for a kids who ends up needing it, or too much of the social life revolving around drinking and getting stoned, or whatever in the environment might be “wrong” for a particular kid). </p>
<p>A school where no one would notice if something is wrong isn’t toxic, but it would be a very big red flag for me.</p>
